CLOCK MECHANISM FOR WARPlNG-IVIACHINES.

SPECIFICATION forming part of Letters Patent No. 766,383, dated August 2, 1904.

Application file'l March 30, 1904.

To 11/ mhmn, it 72m, (o/warn.-

Be it known that I, Anoxzo E. RnoAnns, a citizen of the United States, and a resident of Hopedale, county of \Vorcester, State of Massachusetts, have invented an Improvement in Clock Mechanism for Varping-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention has for its object the production of simple means for facilitating the manipulation or setting of the so called warper-clock employed on warping-machines to measure the yarn handled thereby when for any reason it is desired to disconnect or to set the clock mechanism without delaying the operation of the Whole machine. Usually the clock mechanism is operated by or through two cooperating gears, one of which is driven by some rotating member of the warper--as, for instance, the measuringroll and it now necessary to expend considerable time and trouble in effecting the disengagement of said gears if it is desired to throw out of operation or to set the clock mechanism, involving loss of product due to stoppage of the warper while the gears are being disengaged.

In my present invention I have provided means whereby the clock mechanism can be thrown out of or into cooperative relation with its actuating means practically instantaneously by a slight movement of the operators hand.

The novel features of my invention as contained in one practical embodiment thereof will be fully described in the subjoined specilication, and particularly pointed out in the following claims.

Figure 1 is a side elevation of a portion of a warper and a clock mechanism with its actuating means with one embodiment of my invention applied thereto, the actuating means being shown in operative condition. Fig. 2 is a transverse view of the parts at the left of the line 2 2, Fig. 1. Fig. 3 is a detail in side elevation similar to Fig. 1, but showing Serial No. 200,714. (No model.)

the actuating means and clock mechanism disconnected. Fig. 4 is a sectional detail on the line a 4, Fig. 1, showing the bearing for one of the gears by which the clock mechanism is operated; and Fig. 5 is a view in elevation ofa member of the locking means to be described.

In the drawingsl igs. 1, 2, and 3,the warperclock C, of usual construction and having a setting-wheel e and a transmitting-gear a, is mounted in suitable manner on the warperframe and near the measuring-roll M of the warper, (see Fig. 1,) the clock measuring the length of yarn which passes over said roll.

The clock, as shown in Fig. 2, has two hands C C, which travel over circular graduations on the face or dial, the hand C being moved ahead one space for each complete revolution of the hand (1 and each revolution of the latter hand usually indicates that a certain number of hundreds of yards of warp has passed through the machine, the clock mechanism fir) .sw forming no part of the present invention.

The transmitting-gearc is usually a wormgear, as herein shown, the clock-casing being cut out, as at (1, Fig. 3, to expose a portion of the gear and permit it to mesh with a worm 1, which forms a part of the clock-actuating means.

The worm 1 is herein shown as mounted on the reduced end 2 of a short shaft 3 (see Fig. 4) and held fast by a washer 4 and screw 5, the shaft being rotatably mounted in a cylindrical sleeve-like bearing 6 and extended through it, a gear 7 being secured to the other end of the shaft 3. The shaft is eccentric to the longitudinal axis or center of the bearing, and the latter is mounted rotatably in a tubular support 8, fixedly secured to a part, as A, of the warper-frame, Figs. land 3, said tubular support being shown as a part of the clock-case.

The gear 7 meshes with a pinion 9 on the shaft m of the measuring-roll, the gearing 1, 7, and 9 and shafts 7n and 3 constituting actuating means for the clock.

Angular movement of the bearing 6 will raise or lower the shaft 3 far enough to cause engagement or disengagement of the drivingworm 1 and the transmitting worm-gear 0 of the clock, owing to the eccentric mounting of the shaft in the bearing. At its outer end said hearing has secured to or forming a part of it a radial arm 10, provided with outturned cars 11, on which is fulcrumed at 12 a latch 13, having an extension shaped to form a handle 14.

The tubular support 8 has a depending portion or keeper 15, provided at one end with a radial notch 16 (clearly shown in Figs. 3 and 5) to receive the latch 13 when the bearing 6 is in its operative position, Figs. 1 and 2, the

Worm 1 and worm-gear c then meshing and the handle 14 hanging down.

When it is desired to disconnect the clock and its actuating means, the operator grasps the handle 14, pulls it outward into dotted-line position, Fig. 2, to release the latch 13, and then moves the handle laterally to the radial position shown in Fig. 3, bringing the latch opposite a second locking-notch 17. Such angular movement of the bearing 6 causes the shaft 3 to move the worm 1 away from the worm-gear c, and the clock is completely disconnected from its actuated means and can be reset or otherwise manipulated, as desired.

hen the handle 14 is in the radial position shown in Fig. 3, it is swung downward on its fulcrum 12 to cause the latch 13 to enter the locking-notch 17 of the keeper to prevent any accidental movement of the bearing 6, and, when the latch is in the notch 16, as in Fig. 1, the bearing is locked, with the clock and its actuating means in cooperation. Between the locking-notches the face of the keeper 15 is shaped to form a beveled segmental face 18, over which the latch wipes when the handle 14 is swung in one or the other direction, serving tokeep the handle thrown out until the desired locking-notch is reached.

By beveling the face 18 the latch is withdrawn from a notch by a smaller movement of the handle on its fulcrum 12 than would be required otherwise, and, as shown best in Fig. 2, a stop 19 is mounted on the handle to engage the arm 10 and limit outward throw of the handle.

It will be manifest that the operation hereinbefore described to throw the warper-clock into or out of action is readily performed and is practically instantaneous, and such operation in no manner interferes with any other part of the apparatus.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In apparatus of the class described, a warper clock, actuating means therefor, means, including an angularly-movable member, to effect engagement or disengagement of the actuating means and the clock, and a manually-controlled device to effect angular move: ment of and also cooperating to lock said memher from movement.

2. In a warping-machine, clock mechanism having a transmitting-gear, actuating, means including a driving-gear adapted to cooperate with the transmitting-gear, a rotatable sleevelike hearing for and in which the shaft of the driving-gear is eccentrically and rotatably mounted, a combined handle and latch carried by said bearing, and a fixedly-mounted keeper, angular movement of the hearing when unlocked causing the driving-gear to move into or out of mesh with the transmitting-gear.-

3. In a warping-machine, a warper-clock having a transmitting worm-gear, a cooperating worm and its shaft positively rotated, a sleeve-like bearing for and in which the shaft is eccentrically and rotatably mounted, a latch and its keeper, one of which is angularly movable with the bearing, angular movement of the bearing moving the worm into or out of engagement with the worm-gear, the keeper having notches to be engaged by the latch to thereby retain the worm in operative Orin; operative position.

4. In awarping-machine, a measuring-roll, a worm and its shaft, gearing between the roll and shaft to positively rotate the latter, a cylindrical bearing for and in which the shaft is eccentrically and rotatably mounted, a warperclock including a worm-gear adapted to mesh with and be driven by the worm,rotative movement of the bearin g causing the worm to move into or out of mesh with the worm-gear, and manually-controlled means to lock the bearing with the worm in operative orv inoperative position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALONZO E. RHOADES.
